Hi,
I converted this c# pop3 mail class to vb.net. Maybe this will
help.

How to use
Dim mail As New Pop3Mail
mail.Connect("mail.xxxx.net", "user", "password")
For Each msg As Pop3Mail.Pop3Message In mail.List
Trace.WriteLine(DirectCast(mail.Retrieve(msg),
Pop3Mail.Pop3Message).message)
Next
The class
Imports System.Net.Sockets
Public Class Pop3Mail
Inherits System.Net.Sockets.TcpClient
Public Class Pop3Exception
Inherits System.ApplicationException
Public Sub New(ByVal str As String)
MyBase.New(str)
End Sub 'New
End Class 'Pop3Exception
Public Class Pop3Message
Public number As Long
Public bytes As Long
Public retrieved As Boolean
Public message As String
End Class 'Pop3Message
Public Overloads Sub Connect(ByVal server As String, ByVal username As
String, ByVal password As String)
Dim message As String
Dim strResponse As String
Connect(server, 110)
strResponse = Response()
If strResponse.Substring(0, 3) <> "+OK" Then
Throw New Pop3Exception(Response)
End If
message = "USER " + username + vbCr + vbLf
Write(message)
strResponse = Response()
If strResponse.Substring(0, 3) <> "+OK" Then
Throw New Pop3Exception(strResponse)
End If
message = "PASS " + password + vbCr + vbLf
Write(message)
strResponse = Response()

Throw New Pop3Exception(strResponse)
End If
End Sub 'Connect
Public Sub Disconnect()
Dim message As String
Dim strResponse As String
message = "QUIT" + vbCr + vbLf
Write(message)

End Sub 'Disconnect
Public Function List() As ArrayList

End Sub 'Write
Public Sub Delete(ByVal rhs As Pop3Message)

Dim bytes As Integer = stream.Read(buff, 0, 1)
If bytes = 1 Then

Exit While

Else
Exit While

End Function 'Response
End Class
